As a long-time participant, and a long-time poster (happily including many posts of content, not just argument), and a long-time believer in the value of free speech (including, but not limited to, arguments which are stupid, annoying and even over-the-line under FT standards), I will mention that I think the Security forum is perhaps the most interesting and most enjoyable forum on FT. I don't know of any other source for equivalent information, even though it is true that some people express harsh comments.
